Recent exponential growth in immersive God Pod units operating in US prisons has engendered many new but still unexamined practices. Loosely-modeled off a Christian seminary planted inside Louisiana State Penitentiary, newer programs deploy privately-funded religious educators for the credentialing and training of “inmate field ministers” assigned religious work duties in public prisons. Funded by private foundations and unregulated by government oversight, Christian educators operating inside public prisons today directly influence the material conditions of incarceration for thousands of inmates. While previous God Pod programs were declared unconstitutional for use of government funding in proselytizing Christianity, newer programs use private resources for conduct of Christian ministry inside public prisons. Drawing from on-site and archival research, this article documents a shift in focus within immersive God Pod units from providing religious education at one institution to credentialing prisoners for “Inmate Field Ministry” systemwide. The article traces the ad hoc beginnings of privately-funded religious education inside US prisons, to today's emphasis on establishing Christian ministry as correctional rehabilitation. The article argues newer God Pod units engender a novel form of religious neoliberalism, abandoning previous commitments to religious neutrality while highlighting “moral rehabilitation” and deemphasizing secular rehabilitation. Directions for future research are discussed.
